Application filed September' 20. 1916.

To ZZ r1li/wm, il? may concern Be it known that L ALPHoNsF, FnnNAN- Dnz. a' subject of the Kingof Spain, residing at the city of Wasl'iington. in the District of Columbia, have invented cert-ain new and useful Improvements in Smoke- Handling Apparatus; and ,l do declare the following to be a full. clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention is designed pri- `mar'ily for collecting the smoke from the furnaces or exhaust gases from the engines of submarines while submerged and expelling it 01 them at intervals under pressure, but it is to be understood that the device is .applicable for instance, to locomotives when traveling through vtowns in which excessive smoke .1s not permitted, and that 1t may m fact be employed wherever applicable.

The object of the device is to provide simple and efficient means for the attainment of the above named results, considerable difficulty having been heretofore encountered in the proper expulsion of the smoke from the furnaces and exhaust gases from the engines of submarines when the latter are submerged with their smoke stacks folded or collapsed.

lith the foregoing general object in view` the invention resides in certain novel features of construction and in unique combinations of parts to be hereinafter fully described and claimed, the descriptive matter heilig supplemented by the accompanying drawing which constitutes a. part of this application and in which a sectional view of f the improved apparatus is shown.

In this drawing the numeral 1 designates a furnace andl has reference to the outlet pipe which is adapted to lead to a suitable smoke stack, said pipe having a branch 3 and having above said branch a damper or valve 4, the branch 3 being also provided with a valve as indicated at 5. Auxiliary branches G lead from the end, of the branch 3 to inlet ports 7 in the opposite ends of a pump cylinder 8, said ends also having outlet ports 9. Through suitable pipes 10 the two exhaust ports 9 discharge into the lower end of a cylindrical smoke collecting chamber 11, a cheek valve 12 being located at the inlet of said chamber. The chamber 11 is vprovided with an outlet pipe 13 having a cut oft' valve 14 and at its outer end an outwardly opening check valve15 which may Specification of Letters Patent.

piston QO is formed with an opening 21' through which a valve shifting rod passes. the opposite ends of said rod passing through the ends of the cylinder and being connected to cross heads 23 having slide valves 24 at their ends for controlling the ports 7 and S). Near its apposite ends the rod 22 is provided with abutmcnts 25 disposed within the cylinder to be struck by the `piston 20 as the latter moves to the opposite ends of the cylinder duringn its reeiprocation, it being understood that the operating means above referred to i; adapted to alternately drive the screw 18 in opposite directions.

During the downward travel ofthe piston 2O the uppermost in-let 7 is open and the upper exhaust port 9 is closed while the positions of the lower-valves are reversed so that the piston will force any smoke within the lower end of the vcylinder S through the check valve 12 into the collecting ,chamber 11. The piston 2O in thus traveling downward strikes the lower abutment 25 and thus shifts the rod 22 so as to move both cross heads 23' to reverse the positions of the valves 24. As piston 2O now rises, smoke is taken into the lower end of the cylinder S and expelled from the upper end thereof and when said piston comes in contact with the upper abutment, the valves will be again reversed. The pump acting in this manne draws the smoke from the furnace 1 and deposits it into the collecting chamber 11 when the valves 4. and 5 are respectively closed and open.

Within the chamber 11 is a smoke expelling piston 26 operated by means of a screw 27 having at its upper end a gear or the lOO like 28 by means of which power may be applied to cause the piston to move downchamber ll.. The descent of piston 26 obxv'iousl);v forces the smoke through the valves llt and l5 and the pipe 13 and ifv the device be used on a submarine, said valve l'prevents any water from entering the apparatus.

The valve lll is merely used as a safety device to prevent the entrance of Water into the aprmratus in case the valve l5 should not operate properly, and similarly, if through an)v accident water should enter the chamber ll and the check valve 12 would not operate to prevent the passage of such water into the pump, a cut olf valve 29 in one of the pipes l0 may be closed by hand.

By constructing the apparatus in the manner shown and described or in approximately this way, it Will be highly etlicient and durable and as above stated is particle larly applicable for use on submarines although it may Well be employed Wherever details hut'it is to be understood that within the scope of the invention as claimed, nu merous changes mayv be made Without sacri- 4tlc-.ing the principal advantages.

It is to be understood that the improved apparatus is not restricted to the handling of smoke since it may well be employed for expelling the exhaust gases of internal cornhustion engines.

1. A smoke or gas handling apparatus for use in connection with furnaces and other gas expelling apparatuses comprising a smoke or gas collecting chamber, a pump for forcing the smoke or gas into said chamber, and means for forcing the collected smoke or gas from said chamber.

2. A smoke or gas handling apparatus for use in connection with furnaces and other gas expelling apparatuses comprising a smo te or gas collecting chamber having therein a piston, a pump for forcing the smoke or gas into said chamber in advance of the piston, and means for projecting said piston to expel the collected smoke. or

gas.

3. A smoke or gas handling apparatus for use in connection With furnaces and other gas expelling apparatuses comprising a collecting chamber, a cylinder having therein-a piston, smoke or gas inlets into the opposite ends of the cylinder, smoke or gas outlets from said ends into the collecting chai'nber, valves for said inlets and outlets, ine-ans for reciprocating said piston to force the smoke or gas into the collecting chainber, and means for forcing the collected smoke or gas from'said chamber.

fl. A smoke or gas handling apparatus for use in connection with furnaces and other expelling apparatuses comprising a pump cylinder having therein a piston, a screw for reciprocating said piston, smoke or gas inlets from the furnace into the opposite ends of the cylinder7 a cylindrical smoke or gas collecting chamber, smoke or gas outlets from the ends of the cylinder into said chamber, valves for said inlets and outlets, a check valve for the inlet of said collecting chamber, an outlet from said collecting chamber, a check valve for this outlet, a smoke or gas expelling piston in the collecting chamber, and a screw for operating this piston.

5. The method of handling smoke from a furnace or other gas expelling apparatus consisting in pumping said smoke or gases into a collecting chamber until the pressure in the latter reaches a predetermined degree, and in then forcing the smoke or gas from said chamber.
